Description

The axial-flow type aerator

The utility model relates to the aquaculture equipment technical field, particularly a kind of axial-flow type aerator.

The aerator that is usually used in culture fishery at present substantially all is vane type and Waterwheel-type, especially use the most extensive with paddle aerator, because two kinds of types all have gear reduction, thereby exist oil impregnate, leakage of oil, gear and damage and then burn problem such as motor, it is unallowable in the fish pond oil impregnate oil leakage phenomenon taking place, it can cause the mortality of fish, so the appearance of these problems brings adverse influence to the development culture fishery.

It is a kind of not with gear reduction and axial-flow type aerator simple in structure, that efficient is high that the purpose of this utility model is to provide.

The purpose of this utility model is achieved in that a kind of axial-flow type aerator, comprises motor, straight tube, power transmission shaft, rubber lower bearing, impeller, floating drum, frame, and described motor output shaft is equipped with thrust bearing, sealing ring and thrust annular groove; The described shaft coupling that is connected between motor output shaft and the power transmission shaft is the positive coupling of tape spool to the location; The impeller that is contained in the power transmission shaft lower end is provided with guiding gutter and taper diffusing opening; Straight tube is housed between described straight tube and the frame to be clamped and angle demodulator.Be provided with binary at least guiding gutter in the wheel hub of described impeller.Described positive coupling clamps motor output shaft end and transmission axle head by bolt, nut, becomes rigid attachment, and the endoporus middle part of this shaft coupling has two cannelures, and the thrust snap ring is housed in the groove, becomes axial positioning structure.On the straight tube pipe shaft clamping ring is housed, its both sides rotating shaft is fixed on the frame by bearing block support, and the locating ring on registration arm also being housed and being loaded on frame on the described clamping ring is movable to be connected, and frame is fixed on two floating drums.

The utility model is to have utilized existing small axial flow pump technology by the design improvement to impeller, air deflector, straight tube and spindle drive, guiding gutter and taper diffusing opening particularly in impeller hub, have been designed, impeller changed into by water lift push away water function, the thrust of utilizing its high speed rotating to produce, form very strong negative pressuren zone under water, force air to suck and the abundant mixed dissolution of water, reach the purpose of dissolved oxygen oxygenation from the straight tube upper port.

Compared with prior art, advantage of the present utility model is: saved gear reduction, overcome oil impregnate, leakage of oil and gear fully and damaged phenomenon, simultaneously, it is simple in structure, and is easy to maintenance, and power drain is few, and oxygenation effect is obvious.

By following embodiment the utility model is further elaborated.

Referring to Fig. 1-shown in Figure 6, an embodiment axial-flow type of the utility model aerator is made up of motor 1, shaft coupling 2, power transmission shaft 3, straight tube 4, clamping ring 5, locating ring 6, lower bearing 7, impeller 8, floating drum 9 and frame 10, motor 1 output shaft 11 is equipped with thrust bearing, sealing ring and thrust annular groove, in order to prevent causing the motor counter-rotating because of accident, gush on the current, may enter in the motor winding and damage motor.The shaft coupling 2 and power transmission shaft 3 rigid attachment of motor 1 output shaft 11 by having axial location, shaft coupling 2 in two by flat key 202 and four bolts 201 with motor 1 output shaft 11 and power transmission shaft 3 rigid attachment, this shaft coupling 2 endoporus middle part has two thrust annular grooves, and the thrust snap ring 203 of packing into, thereby realize axial location.In addition, two bolts 12 that shaft coupling 2 is axially installed are used to regulate the gap of motor 1 thrust bearing, to bear the axial force that produces when impeller 8 is worked.The rubber lower bearing 7 that is used to support the location is equipped with in described power transmission shaft 3 bottoms, it is made up of powder metallurgy axle sleeve 701 and rubber shaft bearing 702, it not only is convenient to maintenance update, and because rubber shaft bearing is lubricant with water, have better elastic again, being in operation to absorb and to eliminate issuable vibration preferably.Impeller 8 is equipped with in power transmission shaft 3 lower ends, be cast with the guiding gutter 802 of three five equilibriums in its wheel hub, the lower end is provided with taper diffusing opening 801, and when impeller 8 high speed rotating, water is subjected to the powerful vortex that promotes to produce, form a very strong negative pressuren zone, negative pressure makes air enter from the air inlet of straight tube 4 tops, through straight tube 4, wheel hub guiding gutter 802, discharges from taper diffusing opening 801, mix with the current of strong disturbance, thus the dissolved oxygen in the increase water.In the clamping of between straight tube 4 and frame 10, being adorned and angle demodulator, the clamping ring 5 usefulness pinching screws 502 of two ends band rotating shaft are fixed tightly on straight tube 4 pipe shafts, be installed in diaxon bearing 101 and be fixed on the frame 10, two floating drums 9 are supporting complete machine and are floating on the work water surface, regulating clamping ring 5 can the main control system underwater penetration, be impeller 8 immersion depths, locating ring 6 usefulness bolts on registration arm 501 also being housed on the clamping ring 5 and being loaded on frame 10 are movable to be connected, in order to adjust the operating angle of aerator, the relation of the oxygenation effect of aerator and correct immersion depth and operating angle is very close.
